3 years


up to the German TVöD 13

Type of employment


"Cutting-edge research requires excellent minds – particularly more females – at all levels. Launch your mission with us and send in your application now!" Prof. Pascale Ehrenfreund - Chair of the DLR Executive Board

Ultrahigh temperature Ceramics (UHTCs) are the class of materials that offer great potential to be used in aerospace applications such as wing leading edges and nose cones of hypersonic vehicles, scramjet propulsion, combustion chambers, turbine components and nozzles for rocket and aerospace engines. They provide unique properties at extreme high temperatures that no other material can offer. However, their oxidation behaviour at high temperature (>1500°C) is still a major obstacle for potential applications.

A new approach is proposed for the improvement of oxidation performance of UHTCs and UHTC-CMCs by application of protective coatings that are tailored to chemical compatibility with the UHTC and that drastically lower the degradation of the base material.

The aim of the PhD project is to develop novel coating solutions for this promising class of materials. This development will be carried out in collaboration with Missouri University of technology (MS&T), USA.

Your qualifications:

  • finished university degree (Master of Science) in Ceramics, Materials Science or Surface
  • engineering/technology
  • basic knowledge of ceramic materials
  • good knowledge of the common analytical methods on coatings such as XRD and SEM
  • experience and sound knowledge on oxidation, heat treatments will be an asset
  • good knowledge of German and English in spoken and written
  • proven experience with computer and office products
  • willingness to work in a team of technicians and scientists
  • first practical experience on PVD- processing technology is desirable as well as
  • experience with thermodynamic calculations (CALPHAD) with FactSage or Thermocalc

Your benefits:

Look forward to a fulfilling job with an employer who appreciates your commitment and supports your personal and professional development. Our unique infrastructure offers you a working environment in which you have unparalled scope to develop your creative ideas and accomplish your professional objectives. Our human resources policy places great value on a healthy family and work-life-balance as well as equal opportunities for persons of all genders (m/f/non-binary).
